Massive Star Collision Spotted by Hubble

[RiaX]

Yup. I was wrong

well least now I know the correct data

EDIT:

I always thought its was called an optical telescope from its design.

Hubble's "eyes" are actually a system called the Optical Telescope Assembly. That system consists of two mirrors, support trusses, and the apertures (openings) of the instruments. Hubble's optical system is a straightforward design known as Ritchey-Chretien Cassegrain, in which two special mirrors form focused images over the largest possible field of view.

and not really a purist optical telescope ?

lol im not an astrophysicist or astronomer so if I've been proven wrong I will accept it. There is no shame in saying you wrong only a gain of greater knowledge

This is why science must be argued

Exactly, so don't post as though you are

don't make me act like you and invoke qualifications on this one.

are you qualified in these fields ?

Well im an electrical engineer , i haven't specifically worked on telescopes or anything space related. The company im with does from time to time work on objects that are in some ways similar. So i couldn't tackle these sorts of things from a physics point of view i can address the engineering side of things.

Listen here, buddy. I'm getting tired of your long wided posts everywhere with your so-called pharmaceutical knowledge. This thread is about the Hubble and it's images and you say "I didnt say anything about the hubble" WTF?!

And yes, the Hubble can see through dust, it has what is called a Near Infrared Camera and Multi-Object Spectrometer (NICMOS) which allows it to "see" through clouds of gas and dust that block visible light.

Please stop filling this forum with your unsubstantiated claims.

Uh oh. :erm: Angry abzo is weird abzo.

On that note how does radiation effect computers and electric components? how you shield them from the effects and are they made out of different materials ?

Negatively.

The manufacturing is different to using standard silicone wafers. Besides that they use older more rugged technology & techniques to build things, Schottky instead of CMOS, SDRAM instead of DRAM etc etc. And then they end up 'capping' the ICs etc in metal shielding or boron coatings. These systems are not really powerful but very rugged, I reckon a modern scientific calculator or netbook is way more powerful than the space shuttles onboard computer for example. Besides that everything has double or triple redundancy.

:wtf:

How about a more computer retard explaination ROFL

This is why I dont google these type of things (computer related) will take me like 10 years to catch up

But how does radiation actually damage the computer components, whats the mechanism of action?

By using different radiation hardening techniques, its what adds so much onto the cost of sending this equipment into space. This link might actually answer your question properly http://spectrum.ieee.org/tech-talk/semiconductors/design/radiationhardening-101 .

Sorry if this is not what you are looking for i don't have the time to type out a long essay in response to your question .

If you wanna see actual pics of the universe taken from a "normal" telescope, check out this site - http://www.robgendlerastropics.com/

This guy takes all the pics himself.

lol kinda being spoilt but I prefer it when a specialist explains something within their field. You cant gain the personal element, experience and knowledge that person has by just reading articles. Yes you can gain a lot of knowledge but it is difficult to place it in the right context, a specialist can provide this with their knowledge which is continuously developing and experiences.

Thats why I prefer to ask rather than read on my own. Also its easier when they convert the technicalities for the lay man to understand

@ mercurial

such nice pictures. I wish I had the space and spare money to get these to decorate my house with HD portraits of galaxies

Awesome article carsten, thanks.

Thanks, glad you found it interesting
